Wanted to go with the Infinity Perfect series speakers for my front door speakers. My current Infinity speakers are 2 ohms and the perfects are 4 ohms. I see that will drop my available power to the front door speakers so those may not be a good idea unless I buy two pairs and parallel them at the amp. I would then have two channels of my four channel amp free for possibly driving two of my current Infinity speakers which would be mounted near the subs since I like to sit in the back of my CRV and listen to my system sometimes. If I do that how will it affect the sound or is it not even worth my time to try it.
